Abstract: 1480589 Refractory heat-insulating material FOSECO INTERNATIONAL Ltd 3 Sept 1974 [4 Sept 1973] 41581/73 Headings ClH and ClJ [Also in Division C3] A shaped body of a refractory heat-insulating composition is made by forming a mixture of fibrous material, particulate refractory material and a heat-activatable binding agent, charging a quantity of the mixture into a hot mould, heating the mixture in the mould for a time and to a temperature sufficient to cause the binding agent to bind the ingredients of the mixture to solid self-supporting form, and removing the shape so formed from the mould. The mixture may be dry, or in the form of a damp paste or may be a foamed mixture. The fibrous material may be glass, rock wool, mineral wool, or slag wool. The particulate refractory material may be sand, silica flour, calcined rice husks, chamotte, grog, zircon, alumina, perlite, vermiculite, or other refractory silicates. The refractory material may also be in the form of hollow spheres, e.g. fly ash floaters, alumina microspheres and chromic oxide. The heatactivatable binder may be a thermosettable resin, (e.g. phenol-formaldehyde, melamineformaldehyde, or urea-formaldehyde), a mixture of resin and a curing agent, e.g. furfuryl resin plus acid catalyst or encapsulated liquid resin. The preparations of refractory compositions from silica sand, low density filler, phenolformaldehyde resin and glass fibre (Example 1); silica sand, glass fibre and urea-formaldehyde resin (Example 2); alumina, glass fibre, and urea-formaldehyde resin (Example 3) are described.

Abstract: 1,181,891. Controlling compressors. CATERPILLAR TRACTOR CO. Sept.13, 1967 [Sept.29, 1966], No.41717/67. Heading F1N. A compressor 13 delivering compressed air to a receiver 17 is driven by an engine 11 having a speed governor 29 controlled in response to the air flow through a sensor 22 located in the outlet from the receiver 17. The sensor may be in the form of a Pitot tube, orifice nozzle or, as shown, a Venturi. With the receiver charged and the engine 11 idling, flow through the outlet 20 causes a reduction in pressure in the restriction 23 of the Venturi, the pressure drop being communicated to a chamber 32 by a conduit 24, whereby a diaphragm 33 in the chamber 32 is urged by a spring 36 in a direction causing a rod 34 to operate the governor 29. A valve 38 disposed in the air inlet 14 of the compressor is closed when the engine is idling and is opened, as the engine speed increases, by a rod 51 connected to a diaphragm 49 movable by the pressure in a conduit 43 connected to the engine exhaust manifold or to the inlet manifold 12, if, as described, the engine is turbocharged.

The dotted lines in the Figure show the sequence in which work is lowered into the treatment tanks 1-15. The treatment includes cathodic degreasing, rinsing and Cu, Ni and Cr electroplating. By using the same rinsing tank alternately after an acid and then an alkaline bath, waste water can be neutralized.

Title: Improvements in or relating to the Manufacture of Acoustic Date Carriers or Sound Records
IPC: B29D17/00
Filed: 1968-09-11
Abstract: 1,196,535. Providing films with acoustic data; moulding plastic substances. RICHARD SCHERPE K.G. 11 Sept., 1968 [11 Sept., 1967], No. 43229/68. Headings B5A and B5B. An acoustic data carrier or sound record is made by feeding a plain sheet or film of thermoplastic material to a heating zone wherein a region of the sheet or film surrounded by an unheated region is heated and then feeding the sheet or film having the heated region to a press device for the impression on this region of soundreproducing grooves. As shown in Fig. 1, a film web of synthetic thermoplastic material from which the records are to be manufactured is passed through a printing device 2 in those regions of the film which are ultimately to form the central or label zone of the record. From the device 2 the film web is passed to an assembly 3 comprising adjacent to one another on a common support a heater station 4 and a press station 5. In the heater station 4 the film web is heated over a localized area and subsequently moved by an amount such that the heated area is disposed beneath the press tool. In the press station 5 sound-reproducing grooves are impressed on the heated area and, if desired, the record circumference and the central hole may be punched out in the press station. Alternatively, the latter operations may be carried out in a succeeding device 6. As shown in Fig. 2, in the heater station 4, two heater elements 7 can be arranged one above and the other below the film web 1. Both heater elements 7 have an annular shape, as shown in the plan view depicted in Fig. 3 and are polished bright on the surfaces facing the film web. Each heater element 7 is fixedly mounted on a head portion 8 containing electrical resistance heating elements connected to a power cable 9. The two heads 8 can be moved in guides 10 by means such as the pneumatic cylinder 11, so that when the film web is stationary the heater elements 7 can be brought into contact with the upper and lower surfaces of the film web and can then be retracted, whereupon the film web is again advanced until the next portion of it to be heated is in position between the heater elements. In the plan view shown in Fig. 3 the film web 1 and the annular heated area 12 are indicated by means of chain and dot lines and the appearance of the region of the film after the impression of the sound-reproducing grooves is shown on the extreme right.

Apparatus for driving a stylus 28 relative to a movable chart 32 comprises two solenoids 10, 36, the armature of the unit 10 driving a crank lever 18, 20 carrying the stylus 28 and the lever-type armature 42 acting as a stop to intercept and limit movement of the stylus when the unit 36 is deenergized and to permit full travel when it is energized. The solenoid units are periodically energized through circuits 56, 58 arranged so that the frequency of energization of unit 10 is a predetermined multiple of that of unit 36. A quantity to be measured is represented by an input signal (which may be a varying unidirectional voltage) applied to the terminals of a voltage-topulse-rate converter 62, feeding a "divide-by-two" circuit 64 which in turn feeds both the solenoid unit 10 and a counter 66, which pulses the solenoid unit 36 in response to a predetermined number of pulses from the circuit 64. The unit 36 may be energized in advance of the unit 10 and de-energized simultaneously therewith.

Abstract: 1,129,490. Induction heating. AEG-ELOTHERM G.m.b.H. 26 Sept., 1967 [14 Oct., 1966], No. 43830/67. Heading H5H. [Also in Division C7] A process for the uniform inductive heating of metal workpieces which have continuously changing radii of curvature in the peripheral direction, e.g. cams or cam-shafts, so as to provide a uniform surface-temperature distribution, comprises reducing the frequency of the heating current when the surface with a relatively small radius of curvature has attained approximately the Curie point. An increase of the specific power in the workpiece is carried out simultaneously. The frequency reduction is carried out by using two separately driven generators, the outputs of which are optionally connectible to energy consuming heat conductors and/or heat transmitters, or by using a generator with a polarity reversing driving motor, which is switched to a lower speed of rotation, or by introducing resistances into the rotor-circuit of the drive motor of a single-phase generator, or by using a converter with controllable valves or semi-conductors.
